I can't turn on Bluetooth in Ubuntu 24.04 LTS

  • 772

As many users, I'm having problems with the bluetooth. I'm using Linux 6.8.0-45-generic on x86_64 #45-Ubuntu 24.04.1 LTS, just freshly installed.
When I go on Settings -> Bluetooth and click the toggle to enable, it instantly disables itself.

My laptop is just bought and you can see the full specs here

I tried to follow most of the steps in

None solved the problem.
I cannot remove the battery from my laptop, so I tried the disable/enable on the bios trick but did not help.

The main error message reported is:

  • Bluetooth: hci0: Opcode 0x0c03 failed: -110
sudo dmesg | grep -i blue
[    2.511496] Bluetooth: Core ver 2.22
[    2.511532] NET: Registered PF_BLUETOOTH protocol family

[    4.675379] Bluetooth: hci0: Opcode 0x0c03 failed: -110

But differently from many other people who reported the error, when I check the status of bluetooth.service it says active:

sudo systemctl status bluetooth.service
● bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; preset: enabled)

Does anyone have any tips of what could I try/check?

It's an internal blutooth not a usb one... but added in case I'm missing something.

    That device isn't in the kernel source code yet, in terminal check mokutil --sb as Secure Boot needs to be disabled, then

    sudo apt install git dkms
git clone https://github.com/jeremyb31/bluetooth-6.8.git
sudo dkms add ./bluetooth-6.8
sudo dkms install btusb/4.1

    Reboot
